The fruit which has the greater mass is peach i.e. 150 grams.
What is mass?Mass is a quantity which is used to define that what amount of substance will occupy any space or present in the given object.
We have given,
Weight of apples = 85,000 mg
Weight of peach = 0.15 kg
To compare the quantity first we have to convert both of these units in the same unit, and we know that:
In 1 kilogram = 1000 grams
And in 1 grams = 1000 milligrams
So, we convert both the units into grams as:
85,000 mg = 85,000 / 1000 = 85 grams
0.15 kg = 150 grams
So, the mass of peach is high.
Hence, peach has the greater mass.

2. Calcium hydroxide, used to neutralize acid spills, reacts with hydrochloric acid to produce calcium
chloride and water. If you spilled 85.0 grams of hydrochloric acid and put 120 grams of calcium
hydroxide on it, which one is the limiting reactant? Answer:
Answer:
hydrochloric acid (HCl)
Explanation:
balanced equation: Ca(OH)2+2HCl -> CaCl2+2H2O
85.0/36=2.33 mol HCl
120/74=1.62 Ca(OH)2
2.33 mol HCl x 1 mol CaCl2/2 mol HCl = 1.165 mol CaCl2
1.62 mol Ca(OH)2 x 2 mol CaCl2/1 mol Ca(OH)2 = 3.24 mol CaCl2

Fractional distillation is a type of distillation which involves the separation of miscible liquids.[tex]\rightarrow[/tex]The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

How to know if a single replacement reaction will occur
Answer:
To determine whether a given single replacement will occur, you must use an “Activity Series” table. If the metal or the halogen is above the element it will replace based on the activity series, a single displacement reaction will occur. The video below summarizes an experiment conducted to compare the activities of three metals ( Mg, Cu and Zn ).
Explanation:
Single replacement reaction will occur if any more active specie will add on the solution.
What is single displacement reaction?Single displacement reactions are those reactions in which one element from the given molecule is displaced by some other element.
Generally displacement reactions are shown by metals when more reactive metal is added in the solution of any another metal. Then more reactive metal displaces the metal which is already present in the solution and reaction is taking place is shown by changing in color.

A compound has a percent composition of 38.7% carbon, 9.76% hydrogen, 51.5% oxygen.
Laboratory data shows that the compound's molar mass is 62.0 g/mol. What is the
molecular formula of the compound?
The molecular formula of the compound that has a percent composition of 38.7% carbon, 9.76% hydrogen, 51.5% oxygen is C2H6O2.
How to calculate molecular formula?The molecular formula can be calculated from the empirical formula. The empirical formula of the compound is calculated as follows:
C = 38.7% = 38.7gH = 9.76% = 9.76gO = 51.5% = 51.5gNext, we convert the mass to moles by dividing by their atomic mass:
C = 38.7 ÷ 12 = 3.23molH = 9.76 ÷ 1 = 9.76molO = 51.5÷ 16 = 3.22molNext, we divide by the smallest (3.22)
C = 1H = 3O = 1Hence, the empirical formula of the compound is CH3O
If the molar mass of the compound is 62g/mol;
(CH3O)n = 62
31n = 62
n = 2
(CH3O)2 = C2H6O2

The percent yield of H₂O, if 87.0 g of H₂O is produced by combining 95.0 g of O₂ and 11.0 g of H₂ is 87.87%.
How do we calculate mass from moles?Mass of any substance will be calculated by using their moles as:
n = W/M, where
W = given or required mass
M = molar mass
Moles of 95g of Oxygen (O₂) = 95g / 32g/mol = 2.96 moles
Moles of 11g of hydrogen (H₂) = 11g / 2g/mol = 5.5 moles
Given chemical reaction is:
2H₂ + O₂ → 2H₂O
From the stoichiometry of the reaction, it is clear that:
1 moles of O₂ = reacts with 2 moles of H₂
2.96 moles of O₂ = reacts with 2×2.96=5.92 moles of H₂
Here hydrogen is the limiting reagent as it has lower moles and formation of water depends on this only.
2 moles of H₂ = produces 2 moles of water
5.5 moles of H₂ = produces 5.5 moles of water
Mass of 5.5 moles of water will be calculated as:
W = (5.5mol)(18g/mol) = 99g
Given theoretical yield of water = 87g
% yield of water will be calculated as:
% yield = (87 / 99)×100 = 87.87%

The two effects depends on the nature of a substituent. For instance, species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

In resonance, the species with lone pairs donate electrons while the substituent takes electrons away from another species when deficient by resonance.
What is the Inductive and resonance effect?When the electron donor or the withdrawal groups creates the electron density on the molecule then it is called the inductive effect. This results in the creation of permanent dipoles in the bonds of the molecules.
Atom attached to a benzene molecule with higher electronegativity than hydrogen atom then, it will be an acceptor while with lower electronegativity will be a donor.
The movement of the electron pair like lone pair and pi bond in a molecule by the delocalization is called the resonance effect. The electron donation and acceptance depend on the nature of the substituent molecule.
If the atom attached to the benzene molecule is electron-rich, it will be a donor, while the electron-deficient will accept the electron by the method of resonance effect.
Therefore, the nature of the substituent determines the resonance and the inductive effect.

Acidic oxides are common air pollutants and the source of acid precipitation. Basic oxides are not. Use what you know about these oxides to explain this difference.
Answer:
An acidic oxide reacts with water and produces acid. They are also called acid anhydride, which are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetal or of metals in high oxidation states. An oxide is a binary compound that we obtain upon the reaction of oxygen with other elements. Their chemistry can be systematically understood by taking an oxoacid and removing water from it until only an oxide remains. The resulting oxide belongs to this group of substances. Usually, it is the oxide of non-metals. For example, sulfurous acid (SO2), sulfuric acid (SO3), and carbonic acid (CO2) are acidic oxides. Thus, CO2 dissolves in water to give carbonic acid, and NO2 gives a mixture of nitrous and nitric acids. An inorganic anhydride (a somewhat archaic term) is an acid anhydride without an organic moiety.
Explanation:
